Unlike most coastal restoration projects that seek to fixate dunes, restoration of Nizzanim coastal dunes involved vegetation removal to recreate more mobile-like dune states. This is the largest experimental habitat-manipulation ever conducted in Israel. Since 2004, the LTER researchers have been working directly with the Israel Nature & Parks Authority to monitor trends in natural and restored dunes, and to create knowledge-based conservation management plans. Species diversity has been monitored on several dunes states including mobile, fixed & semi-fixed dunes (un-manipulated & treated) for more than 10 years across four taxonomic groups; plants, arthropods, reptiles & rodents. Such long-term data concurrently monitored across so many taxa is rare in restoration science, and to our knowledge, unique in coastal dune research. Here we present the spatio-temporal changes in species composition & turnover among different taxonomic groups with a focus on arthropods. We use ordination analyses to test for restoration success, using R software. A small but desired shift towards the target state is seen across treatment types, with recolonisation of treated dunes by individual indicator species . Community level restoration success may be achieved over a longer period.
